Workflow action 'Nintex.Workflow.Activities.Adapters.NWQueryList Adapter' is not allowed on site
I had following exception when trying to save imported Nintex workflow:
Workflow action 'Nintex.Workflow.Activities.Adapters.NWQueryList Adapter' is not allowed on site
{"Server was unable to process request. ---> Workflow action 'Nintex.Workflow.Activities.Adapters.NWQueryListAdapter' is not allowed on site https://sitecollectionurl."} System.Exception {System.Web.Services.Protocols.SoapException}
Solution: Go to Central Administration, Nintex Workflow Management, Manage allowed actions and check all actions (as you want). There were all unchecked by default (after installation).
